The operating room is like a battlefield without smoke, and operating room nurses are both warriors and guardian angels for patients, helping patients to resist the attack from the grim reaper in the bloodbath and guarding the safety of patients.

Blood transfusion is like a double-edged sword, it can save a dying life, but without safe, effective, scientific and rational management, it can instantly turn into a demon, leaving the guardian angels in a sorry state and achieving the opposite result.

Do Members still remember the "wrong blood transfusion" incident that happened in Princess Margaret Hospital in Hong Kong? A nurse with less than two years of experience was negligent in not checking the patient's wristband information carefully and mistakenly transfused O+ blood to a patient who did not need transfusion. During the transfusion period, the patient who had been transfused with the wrong blood was fortunate that his blood type was the AB type, which is the "universal recipient of blood", and the amount of blood input was not more than five milliliters, and it was determined that there was no haemolytic reaction after checking. Obviously, the nurse failed to check the patient's identifying information (bed number, name, gender, age, hospitalization number) and transfused the right blood to the wrong patient. This incident undoubtedly once again sounded the alarm for us, carefully checking the patient's information before transfusion and eliminating the mistake of putting the right blood into the wrong patient is always the most important thing.

Blood transfusions are not trivial; if it happens to someone else it's a story, if it happens to you it's an accident, and either way it's a catastrophe for the patient.

So the Guardian Angel takes us through the process of thinking about what other special circumstances exist in the operating room during the day-to-day work, in addition to patient identification information, safety verification, and other issues. For example, intraoperative tour nurses to follow the medical advice to pick up supplies, this time the emergency intraoperative blood transfusion, blood nurses into the room, the surgeon urged to pick up blood, blood nurses should be checked with whom? How to ensure the accuracy of the information? How to avoid a situation where the medical record does not match the surgical patient? Obviously double checking is the unchanging principle, checking wristband information, medical record information, transfusion request form, cross-matching report form, blood bag each item should ensure accuracy. In addition, in addition to the expected blood transfusion, there will be emergencies in the surgery, may be just a case of ten minutes of lumpectomy, the patient will suddenly bleed during the operation, need for blood transfusion, the clinical blood transfusion application form of the temporary issuance of the blood collection information writing, blood collection link checking are worthy of our careful thinking, prudent implementation.

Based on the above, Guardian Angel summarizes the blood transfusion process and cross-matched blood collection process according to the working system and process of hospitals, and according to the working mode of some hospitals: remember not to be inertia thinking!

The above summarized experience may sound simple, but clinical practice always hides all kinds of unexpected safety hazards, the operating room is different from the ward, you never know what will happen next. You never know what is going to happen next. So we need to always identify the right patient, identify the right blood, standardize the right operation procedure, and perform every step according to the standard. Being careful and preventive, the square inch operating room is like a battlefield without smoke, and blood is also the source of energy for this war. Only when the guardian angels go all out with the patients to fight against the disease and ensure the safety of blood transfusion can we finally keep the disease out of the patient's body. Teachers, you are welcome to share with us examples and experiences about blood transfusion.
